I'm not talking about the algorithm, which probably works fine for what it was intended for. I'm talking about the coding style.

1) Round parens array(i) for array indexing was deprecated in favor of array[i] around 1997. Don't expect this to work forever!

2) Uppercase GT/LT/LE/etc and keywords is typical for people using old editors without syntax highlighting. Syntax highlighting should be supported by any decent editor used today. This one is more a matter of taste though.

You still haven't told what you are trying to do or what your signal really is?

* Extract seasonal component? It turns out to be almost not present in the signal you posted.

or

*Fitting a harmonic series to your signal? You need to use more terms, with longer periods then 12 monts.
